Connection diagram of PNP and NPN transistor outputs for electronic pressure switches
| Jürgen Reiser | GeneralManufacturers of electronic pressure switches often offer both PNP and NPN switching outputs. Here is a brief explanation how the two different outputs should be connected. In principle, both are bipolar transistors in which only the internal arrangement of the pn …
What is an electronic pressure switch?
| Sabine Mai | PressureIn the machine-building industry, it has become common practice to use electronic pressure switches. The use of mechanical pressure switches is on the decline. The advantages of the electronic version of the pressure switch are a digital display, adjustable switch …
Ingress protections IP65 and IP67 in one instrument? The pressure switch PSD-30 has it both!
| Jürgen Reiser | GeneralAn important data sheet specification for industrial measuring instruments in general and pressure sensors in particular is the so-called ingress protection. In this context, an alledged printing error in the data sheet of the electronic pressure switch PSD-30 was …
